For example, ( 1 2)LSB linearity for an 8-bit DAC corresponds to 0.195%. It is often given as a percentage or as a fraction of an LSB. Linearity is the maximum allowable deviation from an ideal straight line drawn between the zero-scale and full-scale outputs. An 8-bit, DAC has a resolution of 8 bits, or one part in 2 8. The resolution is the smallest increment of output that the DAC can produce. The resolution of a DAC is given by the number of bits, N. The following is a listing and definitions of key DAC terms and specifications: Digital-to-analog converters are normally chosen for application within a given system on the basis of their resolution and accuracy, which, in turn, is generally determined by N, the number of input bits of the converter.
